I know the lag will increase a little but thats of no concern if it stays under 3500 rpms. If there are any cons please let me know. Also what are the expected power gains from this mod and will this be more tricky to control boost in non-seq form.

thank you,

Car will be louder, no more boost spike to deal with only boost creep. Your non-seq will act like a single turbo, some say it increases power if you do it the real way because you remove the doors etc..etc...
